0678H2500-02 Application Field and Working Principle

Application Field

The 0678H2500-02 is mainly used in protection of low voltage installations and switching of electromagnetic relays. It is suitable for use in industries, construction, transport, public utilities and installations of very high and working networks. Apart from these, the 0678H2500-02 has a wide range of applications such as installations of small and big batteries, ventilation systems, as well a household electrical circuiting.

The 0678H2500-02 has the capacity of withstanding overloads of up to 2.5 times the rated current. This ensures that the fuse has a high operative safety, making it suitable for operations and high power switching applications. As the fuse is UL approved and comes with a UL recognized component label, it is a reliable and safe fuse for a variety of applications that require protection.

Working Principle

The 0678H2500-02 is a thermal-magnetic fuse. This means that it has two types of protection, namely thermal protection and magnetic protection. The thermal protection is due to the fuse\'s material, which starts to melt when the current running through it exceeds a certain level. The magnetic protection is due to the current being kept in control by a magnetic field.

When the current passing through the 0678H2500-02 exceeds the rated current, the fuse starts to heat up. As the temperature rises, the material of the fuse starts to melt. This weakens the thermal connection between the two contacts, causing a rise in resistance. The current then decreases, and the fuse opens, cutting off the excess current and protecting the circuit.

The magnetic protection works by keeping the current flowing through the fuse within control. As the current increases, the magnetic field surrounding the fuse increases, and this reduces the amount of current that can pass through the fuse.

The 0678H2500-02 is designed with the safety of the electrical system in mind. It provides reliable protection against short circuits and protects the other components in the circuit. Furthermore, with its high breaking capacity and low internal resistance, the fuse offers high operational safety.

Conclusion

The 0678H2500-02 is an industrial fuse designed to protect electrical circuits from short circuits and overloads. It is suitable for use in contactors, automation systems, small and big batteries, and more, making it a reliable and safe option for a number of applications. The 0678H2500-02 is a thermal-magnetic fuse, with both thermal and magnetic protection. When the current passing through the fuse exceeds the rated current, the material of the fuse melts, weakening the thermal connection between the two contacts, and the current decreases. The magnetic protection keeps the current within control, protecting the circuit from any overloads. The 0678H2500-02 is a reliable and safe option for many industries.
